My First Unit in Science LIGHT
Hello, I’m back. Today I will be writing about the science unit… Light!
First we need to know about Natural and Artificial. Natural is the light the world made, such as the sun. Artificial light is light that we humans make, such as the lights that are in your room. How do you know if it is natural or not? Okay lets say you see a flash of lightning, do humans make light? No. So that is natural. Anything that Humans make is Artificial.
Now that we know about Natural and Artificial light we need to know about Luminous and Non luminous. Luminous is when objects emit or shows light are called Luminous. Objects that don’t give off light but reflects it are called Non-luminous.
Great, we know that so we need to know how light moves. Light moves by bouncing off things like a table. It is how your room gets bright
OMG!!!! You learned so much already but there is so much more to learn! What is a reflection? What makes a good reflector??? good reflectors are: a mirror and some aluminium foil. Bad reflectors are a carpet and a pencil and so much more!
Okay Okay! You want to learn more, I can tell you more!!! What is Opaque,Transparent and translucent. Opaque is something that you cannot see through at ALL. I did that because: Translucent Is sort of see through but it isn’t opaque, Last but not least: Transparent. Transparent is when something is absolutely see through, like a window.
Here are some videos:
I love science so far and can’t wait to learn more! Bye for now! See you soon or should I say Talk to you soon.
